SAUSAGE-FILLING MACHINE.

Specification of Letters Patent.

Application filed January 28, 1914-.

To all whom it may concern Be it known that I, FRANZ ltoiiwnn, a subject of the King of lrussia, residing at Neumiinster, in the Province of Schleswig- Holstein and Kingdom of Prussia, Gen many, have invented certain new and useful improvements in Sausage-Filling Machines, of which the following is a specification.

This invention relates to sausage filling machines, and consists chiefly of an impr vement in the arrangement and shape of the cut-off valve controlling the inlet and outlet of the filling cylinder whereby the pressure which acts upon the sausage meat in the supply cylinder actuates also the said cut-off va..ve.

An example of the invention is shown in Figures 1 and 2, in which Fig. 1 is a side elevation partly in section, and E i g. 2 a plan view.

The supply cylinder charged with sausage-meat carries on its upper end a plate, upon which is mounted the filling cylinder a and the working gear. The supply cylinder f is divided by a plunger 9 the upper space 0 containing the meat and the lower 29 containing water which is maintained under pressure by a special device hereinafter described. The space 0 communicates with the filling cylinder a by means of the passage (Z into which opens the delivery tube 5. The passage 6! and tube 6 are arranged so near together against the filling cylinder a that they can be controlled simultaneously by one and the same cut-off valve.

In the arrangement shown the cut-off device consists of a vertically moving piston valve 0 which works in the passage (Z so as to close it with its lower end. The filling cylinder communicates with the delivery tube through a cross passage 6 in the piston valve. The downward movement of the piston valve is effected by a hinged arm i pressing upon it under the action of a cam h mounted on the main shaft is, the arm having a roller Z at its free end. The valve rises when the cam it permits through the pressure of the sausage meat from below.

The delivery tube Z) is made rotatable on its axis by means of a pair of bevel wheels m, n, which are themselves driven by a pair of friction wheels 9, 1". As the rotation of the tube must be suspended during the pass ing of the sausage meat, a certain portion of the circumference of one 7" of the friction Wheels is interrupted. The extremity b of Patented Dec. 14, 1911.5.

the tube itself is fluted so as to carry the sau sage skin with it in its rotation.

The plunger 9, dividing the meat space from the water, consists of an upper plate 8 and a lower one 5, between which a packing ring, (or two by means of an intermediate plate) may be introduced. These packing rings are preferably made of fatty material and the edges of the plates beveled toward one another so that when forced nearer together by means of a screw it the fatty ma.- terial is squeezed outward and the tightness of the plunger insured. Should the plates work loose upon the screw thepacking will nevertheless remain effective automatically owing to the opposing pressures of the water and. the sausage-meat upon the faces of the plates. i

The pressure of the water is controlled by a regulator connected with the supply cylinder, consisting of a cylinder 1) in which a weighted plunger 20 moves. The stem of this plunger is connected with the pressure water supply cock 00 in such a manner that the latter is opened automatically by the weighted plunger.

The operation of the machine is as follows :-The filling plunger is actuated by an eccentric 7 mounted on the main shaft 70 through a rod 2 adjustably connected therewith, and upon the back stroke of the plunger, the valve 0 being raised, the sausage meat, (which has been kept under constant pressure in the space 0 by means of the pressure regulator already described) passes through the passage (Z and enters the cylinder 0: without any empty space or air having entered into the latter. The cams 7i, 1 and 1" which are herein clearly described, are mounted on the shaft 71 and consequently move therewith, said shaft being moved by the belt wheel h which is connected to a suitable power element, not shown. When the filling plunger reaches the end of its stroke, the valve 0 is acted on by the cam 72. and arm i, worked from the shaft 76', and uncovers the delivery tube 5, whereupon the filling plunger travels for-= ward and forces the sausage meat into the skin. At the end of this forward stroke the hub 71% and arm 5 set the valve 0 free and the superior pressure of the sausage-meat lifts this valve, thus re-opening the passage between (Z and the cylinder a and closing the delivery tube Z), so that no sausage-meat or air can be sucked back therethrough.

The delivery tube is set in rotation during the back stroke of the filling plunger, by means of the gearing already described, in order to twist the sausage-skin, the Valve 0 meanwhile being stationary.

I claim:

1. A sausage filling machine, comprising asupply cylinder, a filling'cylinder above the supply cylinder. said filling cylinder having a vertically disposed passage-way, a reciprocatin valve operating in the passageway, a tube on one end of the filling cylinder, said valte having an opening adapted to aline with the tube and the filling cylinder, said valve adapted to lie normally in a plane above the filling cylinder, said valve adapted to be moved upwardly by pressure of the meat being forced into the filling cylinder, means for moving the valve downwardly whereby the opening therein registers with the filling cylinder and tube, and means for forcing material into the filling cylinder.

2. .A' sausage filling machine comprising a supply cylinder, a filling cylinder above the supply cylinder, said filling cylinder vhavinga passage-way therein, a revolving tube secured to the filling cylinder, a vertically movable valve in the passage-way,

Copies of this patent ma be obtained for said valve having an opening adapted to aline with the tube and filling cylinder, means in the supply cylinder for forcing material into the filling cylinder, whereby the material moves the valve vertically, a

cam engaging the valve for moving the vale to its normal position, and means in the filling cylinder for forcing material therefrom.

3. A sausage filling machine comprising a supply cylinder and a filling cylinder above the supply cylinder, means for forcing material from the supply cylinder into the filling cylinder, a reciprocating valve adjacent the filling cylinder for controlling the discharge of material from the filling cylinder, said valve adapted to be moved vertically by the passage of material from the supply cylinder, an arm having one of its ends pivotally connected to the filling cylinder, said arm having an enlargement engaging the valve for returning the valve to its normal position.

In testimony whereof I afiix my signature in presence of two witnesses.
